LOUIS LEDERER, OF FARMINGDALE, NEW JERSEY.

PACKAGE-FASTENING DEVICE.

Specification of Letters Patent.

Patented N ov. 28, 1916.

Application Ied March 5, 1914. Serial No. 822,745.

To all whom t may concern Be it known that I, Louis LEDERER, ay citizen of the United States, residing at Ii`armingdale, in the county of Monmouth, State of New Jersey, have invented certain new and useful Improvements in Package` Fastening Devices; and I do hereby declare the following to be a full, clear, and exact (flescription of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the saine.

This invention relates to improvements in fastening devices, and particularly to de- -vices for fastening envelops, bags, boxes, or the like.

The principal object of the invention is to provide a simple and eilicient, as well as cheap fastening device for a package for use in express or p-arcel post service.

Another object is to provide a device of this character which is readily attachable to a package now in use to form an eifective means for holding the package in closed position.

Other objects and advantages will be apparent from the following description, when taken in connection with the accompanying drawings.v v

In the drawings: Figure 1 is an elevation of an envelop showing my invention in applied and locked position. Fig. 2 is a vertical section on the line 2-2 of Fig. l, slightly enlarged. Fig. 3 is a similar section showing the parts before engagement. F ig. Je is a plan view of the blank from which the fastener is formed.

Referring particularly to the accompany- .ing drawings, 10 represents the front wall of an envelop and 11 the rear wall thereof, said front wall being provided with a closure Hap 12. This iap is formed with a transverse slot 13 in the free end thereof.

rIhe fastening device is formed preferably of thin pliable metal such as tin, brass or the like which includes an elongated body portion 14- formed with a transverse slot 15 adjacent the inner end thereof. Extending laterally from both sides of the inner end of the body portion are the wings 16. Extending centrally from the inner end of the body portion is a reduced tongue 17. The upper portion of the rear wall 11 of the envelop is formed with a pair of vertical parallel slits through which are received the said wings 16, said wings being first bent on the dotted lines 19. After the wings have been inserted through the slits they are bent atly against the inner face of the wall 11. The body portion le is then bent on the line'QO and passed through the slot 18 of the flap of the envelop, while at the same time the tongue l? is bent upwardly on the line 21 and its free end inserted through the slot 15 and the body portion together with the tongue bent downwardly against the outer face of the rear wall of the envelop as clearly shown in the drawing.

By the interlocking engagement of the tongue 17 with the body portion, disengagement of the body portion from the slot 13 of the flap of the envelop is effectively prevented. A package closed by such a device as this can be transported through the mails or by express without danger of the package coming open.

To open the envelop the tongue 17 is bent upwardly and then the body portion .bent upwardly so that the tongue 17 will readily disengage itself from the slot 15. The flap 13 can then be disengaged from the body portion so as to gain access to the interior of the envelop.

What is claimed is The combination with a. package closure having aslotted iiap and rear wall, of a fastening' device formed of a thin flexible piece of sheet metal andcomprising an apertured body portion having wings extending at right angles from the lower side edges thereof, and a reduced tongue projecting from :its lower end, the said wings adapted to be. inserted through the slots in the rear wall and bent to lie upon the said rear wall for retaining the said fastening device thereon, the apertured portion of said body adapted to extend through the flap slot and to be bent downwardly into engagement with the outer face of the iiap, the said tongue being adapted to be disposed through the aperture of the said body portion.

In testimony whereof, I aflix my signature, in the presence of two witnesses.
